ANALISIS KESALAHAN SISWA KELAS VIII SMP NEGERI SATAP 1 TINOMBO SELATAN DALAM MENYELESAIKAN SOAL CERITA SISTEM PERSAMAAN LINEAR DUA VARIABEL BERDASARKAN METODE NEWMAN
Full text linkThis study aims to describe the errors of grade VIII students at SMP Negeri Satap 1 Tinombo Selatan in solving story problems involving two-variable linear equation systems using the Newman method. Newman’s method identifies five types of errors: reading, understanding, transformation, process skills, and coding. This research employs a descriptive qualitative approach. The subjects include three students with different mathematical abilities: one high-achieving student (A), one medium-achieving student (T), and one low-achieving student (S). Data collection techniques involve written tests and interviews, with data credibility ensured through member checking. The data analysis process includes data condensation, data presentation, and conclusion drawing. The results indicate that none of the subjects experienced reading errors. However, all three made mistakes in understanding the problems. Subject T did not write what was asked in problem one and misidentified the question in problem two. Subject S also failed to state what was asked in problem two. All subjects struggled with transformation errors, mainly due to incorrect variable assignments. Subjects A and S made errors in problem two, while subject T also struggled with proper notation. Regarding process skills, subject A could not complete the division operation, subject T failed in algebraic manipulation in problem one and miscalculated multiplication in problem two, and subject S did not proceed to the next step. Finally, all three subjects made coding errors. Subjects A and S did not write conclusions, while subject T omitted and incompletely stated conclusions for problem two
PROFIL PENYELESAIAN SOAL CERITA POLA BILANGAN PADA SISWA MTs ALKHAIRAAT TOMINI DITINJAU DARI EFIKASI DIRI
Full text linkThis study aims to obtain a description of the results of solving number pattern story problems in grade VIII MTs Alkhairaat Tomini students from the perspective of self-efficacy. This type of research is descriptive research with a qualitative approach. There are two subjects in this study, namely, subjects who have high self-efficacy and subjects who have low self-efficacy. The results of this study show that (1) related to understanding problems, subjects with high self-efficacy can mention and understand problems well, while subjects with low self-efficacy can mention information even though not as a whole. (2) in planning the problem solving, both subjects can determine the problem solving plan well, (3) in implementing the problem solving plan, the two subjects are consistent with the plan that has been made previously although, there is a mistake when the subject with low self-efficacy enters the value into the formula so that the results obtained are not correct. (4) related to re-examining the answers, subjects who have high self-efficacy re-examine the steps of the question processing process, while subjects who have low self-efficacy do not re-examine the steps to solve the questio
ANALISIS KESALAHAN HASIL UAS MATEMATIKA SISWA KELAS VIII SMP N 2 GALANG
Full text linkThis study aims to Getting a description of errors and factors that cause errors in doing UAS for grade VIII students of SMPN 2 Galang, knowing the teachings of 2023-2024. This research is a descriptiveresearch with a qualitative approach. The subject of this study is to take 12 students of grade VIII SMP N 2 GALANG based on the value of UAS results under the KKM and teacher recommendations that can represent the answers of other students' mistakes. The researcher selects the subject by looking at the results of the student's final semester exam. Values that are below the MMC (minimum completeness criteria) will be analyzed for errors. The standard of KKM scores set at school is 75, so that students' UAS scores that are less than 75 are analyzed for errors. The results of this study show the types of mistakes made by grade VIII students of SMP N 2 Galang based on Newman's procedure: (1) errors in understanding. (2) errors in transforming, (3) errors in process skills, and (4) errors in writing the final answer. Factors that cause errors: (1) lack of students' understanding of the material that has been taught. (2) mastery of basic mathematical skills in the form of weak mathematical computing. (3) lack of understanding of concepts that make students easily forget the material that has been learned. (4) the learning model is not optimal, so that students still have difficulties in learning mathematics and tend to consider mathematics as a difficult and confusing subject.
